Measurement invariance of the Wechsler Intelligence Scale for Children, Fifth Edition (WISC-V) 10 subtest primary battery was evaluated across sex, age (6–8, 9–11, 12–14, and 15–16 year-olds), and three diagnostic (attention-deficit/hyperactivity disorder, anxiety, and encephalopathy) groups within a large clinical sample (N = 5359) referred to a children’s specialty hospital. Competing models were tested using confirmatory factor analysis (CFA), and a five-factor oblique model corresponding to the publisher’s hypothesized first-order measurement model (e.g., verbal comprehension, fluid reasoning, visual-spatial, working memory, and processing speed) was found to have the best model fit. Multigroup CFA was subsequently used to evaluate progressively more restrictive constraints on the measurement model. Results indicated that full metric invariance was attained across the three groups studied. Full scalar invariance was attained for sex and diagnostic groups. Partial scalar invariance was attained for age-group. The results of this study provide support for the first-order scoring structure of the five WISC-V factors in the 10 subtest primary battery with this large clinical sample.

Wechsler 儿童智力量表的测量不变性，第五版 10-Subtest Primary Battery：可以跨年龄、性别和诊断组比较指数分数吗？

Wechsler 儿童智力量表，第五版 (WISC-V) 10 子测试原电池的测量不变性在性别、年龄（6-8、9-11、12-14 和 15-16 岁）和大型临床样本 (N = 5359) 中的三个诊断（注意力缺陷/多动障碍、焦虑和脑病）组转诊至儿童专科医院。使用验证性因素分析 (CFA) 对竞争模型进行测试，并且与出版商假设的一阶测量模型（例如，语言理解、流体推理、视觉空间、工作记忆和处理速度）相对应的五因素倾斜模型是发现有最好的模型拟合。随后使用多组 CFA 来评估对测量模型的限制性越来越强的约束。结果表明，在所研究的三个组中实现了完全的度量不变性。性别和诊断组获得了完全的标量不变性。年龄组获得了部分标量不变性。本研究的结果为具有这一大型临床样本的 10 个子测试主要电池组中的五个 WISC-V 因素的一阶评分结构提供了支持。
